Be it known that we, JOHN and Pn'rna F. Haonnrr, citizens of the United States, residing at Phillipsburg, in

he county ofWarren and State of New Jersey, have invented certain new and use-.

- ful Improvements in 'PortableTracks and TireProtectors; and we do declarethe following to be a full, clear, and exact descrip- 1 others skilled in the art to which it apper:

tion of the invention, such as will enable ftains to make and use the same.

This invention relates to traction devices and tire protectors adapted to form a part of motor vehicle equipment, and has for its" rixnar' olo'ect the rovisionof. a device P i P adapted to assist a motor vehicle, operating arrangement of parts to be hereinafter more under its own power, to climb out of snow drifts, mires or ditchesin which the same which may have become stalled. 1

Another object is to provide atrack may, after assisting the vehicle to climb out of a mire, 'be used as a tire protector and anti-slipping device."

With these and numerous other objects in view, our invent on consistsof-the'novel features of construction, combination and claim.

- Referring to the drawings: Figure 1 is a side elevation of a portion fully described in the specification and of the vehicle wheel and tire showing our protector applied thereto;

'Fig. 2 is a protector; I

"Fig. e'is a perspectiveview illustrating one of theways in which the invention may be used; Fig. 5 shows plan view of a portion of the side elevation of a motor protector applied Fig. 6 is aview of'the attaching chain used with our device.

In describing our invention, We shall refer to the drawings in which simzilar reference characters designate corresponding parts throughout the several views and in which the numeral 1 designates a vehicle wheel, upon the rim of which is mountedia tire 2. This device is adapted to be used in connection with the various types of :vehicle wheels, the size being varied according to the size of the tread of the tire. The device 'fip'ec ificstion of Letters Patent.

,cent edges of each section, so that when the device is used in'traveling through'mud or sand, a minimum space will be afforded for the material to pass through. ."This will afford a traction surface for the wheels, so

that when the device is applied they may be used where ordinarily the vehicle could not travel.

Each steel'section 3 hasa curved inner face 4, which is adapted to fit the triead of the tire 4. as clearly shown in Fig. 3 of the drawing. The outer surface of the section.

is provided with an exteriorly projecting 'rib 5 .is curved transversely with respect to --the tire,

andaextends substantiallyfacross the curved surface of the section.

The sections are provided with laterally wings 6, that extend any projecting sides or the sides of the tire.

desired distance fro These sides are formed integral. with the sections, and project laterally therefrom to afford the traction surface for the wheel.

. They maybe made of any size most advantageous to perform this function. .The

siZeis regulated according tothe type :of

the tire to which the device is to be applied.

The sections 3 are secured to the 'tire ofthe wheel by a pair of flexible connections,

which are preferably wire cables 7, which extend circumferentially adjacent the sldes of the tire and are secured to the innersurface of the sides 6 of the sections, by fasten ing loops 8,.'which have shank portions 9 riveted to the sides. The loops 8 have open ends, so that the cables may beheld positioned in the loops, and the ends bent back so that the cables will be securely held therein. The extremities of the cables 7 areprovided at one end with snap fasteherslO, while the other have apertured fastening plates 1.1 thereon, adapted to receive the v fasteners. This detachable fastening means enables the ends of the cables when positioned around the tire to be secnred together to prevent the sections from slipping therefrom.

For the purpose of securing one end of the track to the wheel when it is desired to assist a vehicle out of a niire, we have provided a chain 12, ha ring a hook 1.3 on each end to be releasa ly engaged with the plates 11 through apertures ll therein.

\Vhen the track has been fastened. to the wheel in. the above stated manner, it is then stretched out in front of said wheel after which the power .is applied and the wheel is guided up the curved inner faces 4 of the sections As the wheat rolls upon the track, the latter is wound. around the wheel. and attains a position whereby the hooks 10 and plates 11 on the ends of the cables 7 may be easily engaged as shown in Fig. 1. When in position, the sections are spaced closely together to afi'ord ample protection for the tire, and a traction surface for the same The projectingrib on each section afi'ords an additional. gripping means when the device is used in traveling through sand and mud.

Owing to the fact that the different sections are loosely connected, this device may be rolled in a small con'i'pact bundle when not in operation, and may beeasily stored. The sections are made of thin steel sheets pressed to the (lGSll'Lll shape, and the curvature 4: is made according to the type of tire to which it is applied. The depth of the same is optional, although it is found most advantageous when the device is to be used, for traction purposes to have the curvature A tire armor comprising a plurality of transversely arranged plates with recesses on their inner faces-adapted to engage the tread of a tire,-wings carried hy the outer ends or said plates and projecting laterally from opposite sides of the tire, said wings having centrally disposed openings there through, rivets in said openings with enlarged heads disposed on the outer surface of each Wing, the inner ends of said rivets extending beyond the inner surface of each wing and being bent to form aiming eyes, a pair of flexible cables. positioning one on each side of the tire and extending through said eyes, and means for coni'iecting the ends of the cables to retain the plates in position.

In testimony whereof we have hereunto set our hands in the presence of two subscribing Witnesses.
